Court records show a man charged with threatening two Republican congressional leaders had 200 rounds of ammunition at his home in Buffalo, New York, along with books on homemade explosives and receipts for two guns.

An agent with the U.S. Capitol Police detailed items found during a search of Carlos Bayon's home in an affidavit filed Friday in U.S. District Court. Bayon is charged with leaving threatening phone messages for GOP Reps. Steve Scalise of Louisiana and Rep. Cathy McMorris Rodgers of Washington.

NOLA.com/The Times-Picayune reports the affidavit says investigators searching Bayon's home found rifle and shotgun ammunition. They found no guns but discovered receipts for an SKS assault rifle and a handgun.
